... or low BMR that also differed with respect to parental effort. We used fixed size cross-fostered families and recorded litter mass daily until the 14th day of lactation. Midway through the experiment (day 8) half of the mothers from each group had fur from the dorsal body surface removed to increase...

...Brian K. McNab ABSTRACT The basal rate of metabolism (BMR) is the most reported estimate of energy expenditure in endotherms. Its principal determinant is body mass, but BMR also correlates with a variety of behavioral and ecological factors that do not determine basal rate: they are byproducts...

...Michael Briga; Simon Verhulst ABSTRACT Basal metabolic rate (BMR) is often assumed to be indicative of the energy turnover at ambient temperatures ( T a ) below the thermoneutral zone (SMR), but this assumption has remained largely untested. Using a new statistical approach, we quantified...

... lactation. Here, we used a different set of metabolic stressors, which do not induce maximum energy expenditures and yet are likely to expose the potential constraining effect of heat dissipation. We compared the physiological responses of mice divergently selected for high (H-BMR) and low basal metabolic...

Speakman SUMMARY Basal metabolic rate (BMR) is highly variable, both between and within species. One hypothesis is that this variation may be linked...

... 5 m apart. The probability of a reward was set at three different levels, thereby creating a `poor',`intermediate' and `rich' environment. Compared with the rich environment,birds flew 4 times more (2.3 h per day) in the poor environment, and increased DEE by 43% to 220 kJ day -1 (3.7×BMR), within...

... of supply alone provides a sufficient explanation for the allometric scaling of metabolism. Examination of empirical data from the literature of comparative physiology reveals that basal metabolic rates (BMR)are driven by rates of energy expenditure within internal organs and that the allometric scaling...
